    Hello guys, I have one question. Should this valve stay open or closed on my vaillant turbomax boiler? I had fiddled with it because I had low pressure after removing air from one heater. Now I do not know correct position. Like this _ or other way I?

    With it the other way the boiler started flashing from led no 5 and stopped heating

    Also is the pressure too high?
    I am new at this boiler stuff, I just moved to new apartment and I need some schooling.

    Pressure's spot on. Any (ball) valve usually needs to be at 90deg to the run of the valve to be in the off position, slot should be the same.
